"""Regression: author worktree bootstrap from clean control checkout (#892).
#892 is the four-door deadlock where every documented recovery path is closed:
bootstrap refuses control, lock demands an existing worktree, worktree-start
demands a lock, and shell worktree add is outside the sanctioned MCP path.
Root cause: assess_author_issue_bootstrap returned allowed/proven for a clean
control checkout, but bootstrap_permits_control_checkout only accepted
create_issue assessments (task_scope=create_issue_only + empty reasons + full
base-tip field set). Author assessments never satisfied the shared predicate,
so the #274/#604 guards kept the ordinary control-checkout block.
